I currently have a DX8 + AR8000 + TM1000 tx/rx setup, connected to an APM2.5+. Rx power comes from the APM, and APM power comes from the 3DR power module (with a 3S source).
How do I get the APM to "pass through" the 3S source voltage to the AR8000/TM1000 so I can receive voltage data on the DX8 telemetry screen? I get the rx voltage ok, but it's the flightpack voltage I really want.
I have poor hearing, so audible alarms are not that effective for me, and I like the ability to specify the alarm on the dx8; I find off the shelve alarms are 3.3-3.5v, which is uncomfortably low for me.
